Abstract

Ambient dynamic test is applied to a 3-story building in Beijing and system identification is adopted to obtain the natural dynamic characteristics. The amplitudes of time histories recorded by different seismometers are compared. They increase with the floor number and two horizontal amplitudes are larger than the vertical one. Spectra analysis indicates that the spectra values of the recordings on the third floor are bigger than lower floors and Fourier spectra for vertical signals are relatively clearer and more remarkable than two horizontal recordings. Analysis suggests that ambient test is a useful tool for structural system identification.
